Alan, thank you for your detailed email.
At first I also thought that fuel delivery is the problem. But then we
noticed that the engine does not miss a beat when accelerated hard. I think
that a hard acceleration needs more fuel in short time than a slight
acceleration. That was the reason we didn't check fuel delivery. Do you
think that there is be a probability of fuel shortage in the carbs anyhow?
The dizzy rotor was replaced, with the whole dizzy.

Eric -
I have found that almost always when you have "missing" under acceleration
or higher RPMs when you start accelerating that it is typically a fuel
delivery problem. Common culprits are rust in the tank that fouls up the
fuel filters or fuel pump. Also, if you have fiddled with the fuel tank
recently (maybe etched and coated it?) that can also be a contributor. A
fuel pump that is failing can also cause this problem.
If there is a fuel filter on the fuel line, try replacing that first with a
new, clean filter.
An easy diagnosis is when the car starts "missing" immediately switch off
the ignition and coast to a stop on the side of the road. Pull off the top
of the float chambers on the SU carbs - if the float chambers are half empty
or dry, this is your problem.
Last but not least you should always replace the dizzy rotor!
Alan
